GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 400,173, dated March26, 1889. Application filed July 2, 1888. Serial No. 278,736. (Nomodel.)

To all whom it may concern.-

Be it known that I, HAROLD .I. BELL, a citizen of the United States,residing at Gloucester City, in the county of Camden and State of NewJersey, haveinvented new and useful Improvements in Gas-Governors, ofwhich the following is a specification.

My invention consists in a gas-governor or gas-regulating burner of theconstruction hereinafter described and claimed.

In the annexed drawings, Figure 1 is a vertical section of a portion ofa gas-regulating burner illustrating my invention. Fig. 2 is anelevation of the base and inner portion of the gas-governing device.Fig. 3 is a horizontal section on the line 00 o: of Fig. 2. Fig. 4 is aperspective of the float-valve.

The numeral 1 designates the base of the gas-governing device, and 2 theshell which forms the casing and supports the burner.

The base 1 is formed with an internally-screwthreaded neck, 3, forattachment to a gasfiXture,and with an externally-sorew-threadedshoulder, 4, that engages internal threads in the lower end of the shellor casing.

Above the neck 3, and communicating therewith, is a tubular stem, 5,having a series of lateral gas-exits, 6, that are located in an annularcountersink, 7, about midway the height of said stem. The tubular stem 5is closed at the top.

Surrounding the tubular stem 5 is a tubular valve, 8, the lower end ofwhich normally rests on the flat upper surface of the base.

The upper portion of this tubular valve is provided with lateralopenings 9, that correspond with the lateral gas-exits 6 of the tubularstem 5, and immediately above these open ings 9 is a disk-float, 10,that is attached to or formed on the valve. .It will be seen that bothends of the tubular valve Sare open. The periphery of the disk-float 1Oapproaches but does not touch the vertical wall of the shell 2, anannular gas-passage, 11, being left 5 between the disk and the casing orshell. This casing or shell is cylindrical in form and has a nipple orpillar, 12, for the attachment of any suitable burner. The gas thatenters the tubular stem 5 passes out through the openings 6 and 9 intothe shell 2 beneath the disk-float 10, and then upward around theperiphery of said float to the upper part of the shellor casing and ontothe burner. If the pressure of gas in the shell 2 is very great, it willcause the float l0 and Valve 8 to rise, thereby diminishing the flow ofgas at the openings 6 and 0 and regulating the pressure at the burner.

It will be observed that no matter what lateral position the tube 8 mayassume on the tubular stem 5 the annular countersink or groove 7, formedin said stem, will prevent any obstruction to the flow of gas throughthe openings 6 and 9, which might otherwise occur by a partial rotationof the tubular valve.

In another application, Serial No. 278,735, of even date herewith, Ihave described and claimed a gas-regulator having atubular perforatedstem closed at its upper end and surrounded by a tubular open-endedvalve provided with lateral vperforations and carrying a disk-float thatoperates in an annular opentop chamber or cup surrounding the tubularperforated stein, a gas-passage being provided I through the lower partof said cup, which gas 7 5 passage is controlled by an adjusting-screwlocated in the base of the regulator. In my present invention the cupand adjusting screw are dispensed with, and the disk-float 10 is fittedwith sufficient looseness in its sur- 8o rounding shell or case toafford an annular passage, 11, for the exit of gas to the burner.

I am aware that a gas-valve has heretofore comprised alaterally-perforated tube closed at its upper end by a disk-float; butthis I do not claim.

In applications Serial Nos. 27 8,7 32, 27 8,7 33, and 278,737, of evendate herewith, I have shown gas regulators comprising a two-part shellhaving an internal tubular laterally-per- 9o forated stem closed at itsupper end and pro vided with a guide for a flaring conical float, whichoperates in a cup surrounding the base of said tubular stem,the floatbeing provided with an internal tubular valve to control thegas-openings of the stem. In each of the above-mentioned applicationsthe float-valve is shown with a lower flaring end, which fits somewhatclosely in the surrounding cup without binding therein, and agas-passage to the burner is all'orded through an opening in the bottomof the enp, which is controlled by an adjnstingserew in the base of theregulator. In an ap iilieation Serial No. 278,7;3-l, of even dateherewith, l have shown a construetion in which the canitrollablegas-passage through the bottom oi? the eupisomitted,and the eoniealfloat-valve titled loosely in the cup in such a manner as to provide anannular gas-passage between the cup and valve. By my present inventionl. dispense with the cup and the eonieal valve-float, and I attach tothe tubular valve a dislelloat, wliieh tits loosely within the upperpart of the regulator-shell, thereby ailfording an annular gaspassagebetween said disk and shell. This construction differs from thatdescribed in my application Serial No. 278,735 tieulars hereinbel'oreexplained.

I would have it nnderstomfl that [do not in the parbroadly claim agas-governor having a t-ubular perforated valve provided with adisklloat; but

'hat I claim. as my invention In a gas-governoror gas-regulatingburner,the combination of the base 1, having a tubular stem, 5, closed at thetop and provided with lateral gas-exits (5, located in an annularcountersink, 7, the upper shell, 2, and the tubular valve 3, havinglateral openings 9 and provided with a disk'lloat, 10, fitting looselyin the surrounding shell, an annular gas-passage, 11, being providedbetween said float and shell, substantially as described.

In testimony whereof I at'lix my signature in presence of two witnesses.
